Emily Stone curled her lip, pondered for a brief moment, and replied, "895051920."
"My goodness!" Oskar exclaimed excitedly, jumping up from his seat and hopping around on the carpet, "Sister Emma is so amazing, really amazing!"
Tara Summer stared at Emily Stone in astonishment, her expression one of sheer amazement, never having expected Emily Stone to be so remarkable.
"This lady is truly impressive, the answer is correct." The maid Lisa, who had prepared lunch, looked at the calculator on her phone and showed a shocked expression.
Lisa would often stand by when she had nothing to do and whenever Tara Summer posed a math question to Oskar, she would follow along with her calculator, which had become a source of fun for her.
Oskar was currently capable of multiplication and division up to four digits, and although he could handle five digits, it would take him about ten seconds to think it through.
